What to know about heat loss surveys in Swindon
The question for a Swindon home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Design outdoor temperatures for Swindon and the wider Wiltshire come from local cold-weather data, not a national average. Homeowners in Swindon thinking about insulation work can use the survey to see how it would change their heat pump size.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Self-builders and architects who need emitter and system sizes early
What's included
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
- Radiator schedule with any upgrades needed for each room
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
The survey in Swindon includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Swindon can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

How long is the heating season in Swindon?
On the shortest day Swindon gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat loss surveys in Swindon: questions
Can you service a heat pump in Swindon that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Swindon, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Swindon?
Survey dates depend on how busy installers are in Wiltshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Marlborough as well as Swindon?
Yes. We arrange surveys and installation in Marlborough, which is about 10 miles south of Swindon, and across Wiltshire.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
